forget it I used a texture hack on mw2 of REPZ and was banned for life. the problem and I have tried to use other account and reset the modem and reinstall the game and I have them banned all other accounts! although I do not understand how they did it because I could not even play and especially I did not use any kind of hack. boooo! you know something? I asked their leaders but I have yet to respond.

And to change that you would have to use an HWID/GUID changer, and that can be a little more tricky.
Reseting your Modem won't give you an new IP, using a VPN will, or request to get an new IP from your provider.

Well, sometimes private servers like REPZ fade out, and get almost no support as it's a dieing community. (Dunno if that's true in this case tho)
Or maybe they just ignore reports like that and ignore it.

a moderator of the forum of cod mw2 told me this "Um yeah ... Your hardware ID is banned not your IP adress.
There is no way you can change your hardware id ...
And if you Manage to do it, you will still get banned.
Banned is banned and you will not get unbanned. Please,
do not contact any other forum moderator or post something
about this or you will get banned from the forum to.
I'm sorry. Rules are rules. Even I have to follow them "
according to you, which means? that changing the serial number of the motherboard and the hard disk and the ip modem return to play?
for hard disks put the programs on purpose.
for motherboard say just take out the battery to that for 1 hour and the serial number is reset and the next restart say that recreates another different.
my modem does not know exactly what or what I can do .booo.

You can ignore your Modem, that has nothing with this to do as they say.
To change your HWID you need an HWID Spoofer. Just google it and you will find tons of tutorials on how to do this.
